Actually, he said it's up to the MMO publishers, in which case, Yoshi-P has said previously shortly after the PS4 reveal and "Crystals Call" trailer came out, that they wont be requiring it. All OTHER online games (like CoD/GTA/Killzone etc) will need PS+.
I mean think about it, why would anyone want to pay three times (purchase, sub and PS+) with two on-going subs? The only thing I know that does that is Xbox Live + Netflix (and other streaming services on Xbox).
